f OUTLET-FIXTURE FOR CONDUITS.

To all whom it may concern:

Be it known that I, HENRY T. PAIsTE, a citizen` 'of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Outlet- Fixtures for Conduits, of which the following isa specification.

My invention relates to-fixtures particularly designed for use withconduits carrying electrical conductors and more particularly with thattype of fixture designed for the support of an incandescent lamp socket.

One object of my invention is to so construct a Lxture of the type abovenoted, that the lamp socket pro er, aswell as its insulating case orshell, sha lbe provided with a substantial support and be rigidly heldin place; it being also desired that the fixture shall be available forvthe connection or attachment to it of a conduit or conduits regardlessol whether they are or are not provided with threaded ends.

I Vfurther desire to furnish' au outlet Alixture provided with one ormore outlets for the reception of a conduit or conduits, each of whichoutlets shall have a threaded as well as an Unthreaded portion and alsomeans for holding a conduit rigidly in place either when it is looselyinserted in the socket or when it is screwed therein.

These and other advantageous ends I secure as hereinafter set forth,reference being had to the accompanying drawings, in which:-

Figure 1 is a side elevation of one form of my improved fixture; Fig` 2is a longitudinal vertical section of the fixture shown in Fig. 1,-Y'Fig. 3 is a transverse vertical secon the line 3 3, Fig. 2, Fig. 4 1sa perspective view of a fixture; the lamp socket and its protectingcover being omitted; Figs. 5 and 6 are side elevations of various formsof fixtures constructed accordin to my invention g and Fig. 7 is a plano? another form of fixture.

Referring to Figs. l to 4 inclusive, A represents a casting providedwith two outlets a, constructed for the reception of conduits B and B',and it will be noted that each of said outlets is provided at itsextreme inner portion with a relatively short threaded section a', whilethez remainder of .its interior is Unthreaded. Each outlet has a setscrew a2 so placed that it may be made to engage the cylindrical surfaceof that portion of a con,

duit inserted within said outlet.

The casting A has vthe sides of its main portionflare( as shown best inFig. 4, so as to form an approximately rectangular opening upon whichmay be mounted a protective casing C, usually of insulating materialsuch as porcelain, within which is placed a lamp socket D. The openingin the casting A is-provided with inwardly projecting lugs a3 for thereception of screws c whereby the casing C is held in place, and thereare also inwardly projecting ledges (Vt for the reception of the lampsocket D. Said socket is the unthreaded part of provided with a shell ofthreaded in this case i'or the reception of an incandescent lamp,

and has also a terminal plate d mounted centrally Y This plate is heldto the porcelain or other base piece d4 of the socket by a screw cl2 andis extended down one side of said base picee, as shown in Fig. 3, whereit is provided with a terminal screw (Z3. The shell il" is held to thebase piece by screws d5, 'which also serve to electrically connect to ita plate (Z6 having a lug extended down the side of the base pieceopposite the extension of the plate d and provided with a secondterminal screw d?.

With the above arrangement of parts it will be noted that when theprotecting casing or covering O is firmly mounted upon the casting A bymeans of its screws c, it engages the projecting ends of the base pieced4 of the socket D so as to rigidly hold these between itself and theledges a4.

By theabove described construction of the outlets it is possible toemploy my fixture with a conduit or conduits regardless of whether ornot the latter is threaded, for in the event of threads being providedon the end of a length of conduit to be run into the `fixture, saidconduit is screwed in place 1n the customary manner, and if desired, theset screw a2 is set down upon it. If, on the other hand, the conduit beso bent that 1t can not be screwed into the .fixture or if its positionbe such that a wrench can not be applied to it with convenience, it issimply entered into the outlet, until it strikes the threads and the setscrew a2 firmly set down upon it:

It is of course immaterial as to what shape be viven the casting A, aswell as how many outIets are provided or the positions they are givenrelatlvely to the lamp socket opening.

at the bottom of said shell. 'I

ing is placed in the bottoni of the casting A2 i on a line with thelanip socket opening; and in Fig. ture casting one end as shown in Fig.5.

In Fig. 2, it will be seen that While the eonv duit B is threaded, theconduit B is unthreaded and only projects into the outlet up to thebeginning of its threaded portion. l

l. A fixture consisting of Aa hollow structure having an opening for thereception oil a conduit, said opening benig Unthreaded Within its outerportion but liaiing at its inner portion threads for the reception ofthe .threaded end of a conduit, with means for holding a conduit in theuiitlireaded portion.

7, the conduit opening enters the i'ix- A3 at one side instead of at the2. A fixture consisting of a hollow structure having an opening for thereception of a conduit, said opening being Unthreaded Within its outerportion but having at its inner end a relatively short threaded portion,with a set screw for holding. a conduit in the unthreaded portion ofsaid opening.

3. A fixture consisting of a hollow struc.- turehaving a plurality ofopenings, a lainp socket mounted over one of said openings, anotheropening having its inner end threaded and its outer portion unthreaded,with means for holding a conduit in the unthreaded portion.

ln testimony whereof, l have signed my naine to this specification, inthe presence of two subscribing Witnesses.
